To all whom t may concern Be it. known that I, DAvfm E.` BnAm, of the city of, Montreal, inthe" .Province of' Quebec and Dominion of I Canada, havein vented certain` new and useful Improvestrong not only to sustain the load but to resist the strains jected. l

' The main vdbject of the invention is to provide a carbody of improved construc- .tion that will be suiiiciently strong to carry the loadand resist the variops strains to whichit is subjected; that can be quickly and easily turned to one side to discharge the load through side doors that will operate"automatically upon the release of the car body; and that can be returned toits normal position witl-great facility. For

to which the ear is sub- A particulars of operating mechanism, referlence may be had t'o my'y complementary ap plication, Ser. No. 5I6 874'.

In the drawings 'which illustrate"my in` ventionz. Figure 1 is a plan view of a car constructed according to` myl invention. `lilig. 2 is a side elevation of the 4car shown in Fig. 1, the left halbeing in central lpngi- -tudinalsection. Fig'. 3 is an end elevation ofthe car. Fig. 4 is a transverse sectional view on the line 6`7 ot Fig. 2, the broken lines showingl the. car intilted position.

Fig. 5 is a perspective view of one of the compartments of the car showing the side doors and the locking mechanism thereforn The body of the car constructedaccording to my invention, is divided into a series of compartments byA means of transverse par?, titionsl or diaphragms.

Referring to the drawings, 8 designates the compartments, and 9 the 'diaphragr'ne or vside by the partition or diaphragm 9.

partitions separating same. In 'the View shown in Fig. 5, the end compartment'. is bounded-` upon one side by the vertical'end wall 12 vof the car, and upon-'the opposite each compartment, said side plates constitutng the ixd side wall of the ear-body. AThe side plates 11a-re' connected to the diailoor 10 is fixed to the side-plates by meansv y of the" angle-bars 14e. y

l5 designates' the angle-plates connecting the floor member 10 with the da hr'agms 9, said diaphragms 'beinga provide at the top with angle-bars 16 to stiifen them. The angle-bars 15\and 16 with the connecting plates or diaphragms 9, form girders which sup ort the car-body and preventsame from bersare very essential inthe construction of centrally and mounted to tilt pivotal upon segments underneath the car-body. T e Acar- *extend longitudinally underneath the saine throughout its length. End stakes 18.l support and strengthen the end members 12'l'5f the car and are fastened to the angle-bars`17.

three 'vertical sides of each compartment and each being provided at the top with a thickened lip 23, which is adapted to engage the Tlug or catch 24, fixed to the longitudinal intervals throughout the length o the car. `The sha ft 25 is operated by means of a lever 27 fixed to 'the square end 28 of the shaft.

As the car-body is tilted, the link 29 and the' locks or catches 24and releasing the vdoors 20, as more fully hereinafter explained. The doors 20 swing outwardly .uponthe hinges 21 and fall downwardly upon the buffer vbeam 32, which extends along the side of the car, as indicated. The buffer beam' 32 is fixed toa series of hangers 33 mountedupon hinges-34. The hangers 33 are pivotally connected with link members A35 which are pivoted at t eir opposite ends 36 vto the und'erframe; .hen the car -is tilted tb one side, and the doors swung -buc (ling or twisting. f These girder n'fefl'n-n shaft 25 mounted in bearings 26 laced at The lever- 27 is pivoted at its opposite end to the link29 provided with an adjusting delever 27 operate to turn theshaft 25, 'raising-- 1l designates the vertical side plates /of phragins 9 by the anglefplates 13, while the a car of this type, said car being su ported I body is stiifen'ed by angle-bars 17', .which The sides ofthe compartments are stiened and strengthened by the members 19. The

are thus fixed, the fourth side comprising the door 2() mounted upon hinges 2J. beneath said door, said hinges extending upwardly" on the outside of the doors to form braces 22 t of tilting the car.

outwardly and downwardly, they fall against the buffer beams 32, which are held at the proper angle by 'means of the linksv 20 thus assume the position 35. The doors shown in dotted lilies in Fig. 4, and the load is discharged in such a manner that said doors prevent the contents-from falling underneath the car and piling up on the rails and thus blocking the tracks. The load may be scraped away from the car doors, if necessary, by any suitabie means.

The car body is mounted upon longitudinal center sills 37 which are supported by the frame holsters 3'8, \the center sills being connected at intervals by stiifening plates 39 and cover plates 40. The car body is mounted centrally upon castings 41, secured to the under side of the car body between the longitudinal angle bars 17, said castings 4l being inl the Aform of a segment curve 42.

his segment is provided with a series of teeth 43Which operate in the cover plates to prevent slipping during the operation d y The center of support of the car body is preferably out of line with the central axis of said car body, in order that the car will dump itself automatically; The car body is provided' on its under side, opposite the doors, with a rack 44, pivoted at 45, said rack coperating with a. pinion'46, actuated by a shaft 47, adapted to revolve in bearing plates 48, suitably fixed to the under frame of the can 49 designates longitudinal supporting members mounted upon the side sill 50, upon which the car is adapted to rest in its normal position.

The operation of unloading the car will be readily understood from the foregoing description. When the .car is loaded in its normal level position, it is held in place bythe engagement of the pinion 46 with the rack 44, said pinion being locked and released by any well known mechanism for this purpose. When it is desired to discharge thecontents of the car, the pinion 46 and shaft 47 are released, and as the center of support of the car body is slightly out of line with the central axis of the car body, and toward the fixed side of the car, said car will automatically tilt in the direction shown in broken lines in Fig. 4, the pinion 46 working easily upon the rack 44. As the car tilts toward the side, the doors are automatically released from the locks or catches 24 and fall outwardly and downwardly being supported by the buiers 32. The contents of the car discharge by gravity. and the doors 2O prevent the load from spreading underneath the trucks.

Having thus described my invention, what I claim is fr car body comprising a continuous iXed side, internal transverse girders Asupported at the approximate centers of their lower edges,a floor, and means connecting said side and said Floor to said transverse girders,

whereby said floor and side are supported from said girders. in witness whereof have hereunto set my hand in the presence of two witnesses.
